If you really wanted to be sure, go to OB for proper check-up. Kasi, if you're a first time mom, how would you know na nagccrave ka na pala as well as other symptoms of pregnancy? Not all pregnant women experiences morning sickness or paglilihi, iba-iba ang pagbubuntis kahit may anak ka na. Mamaya pregnant ka na pala and you didn't know kakahintay mo sa symptoms. Si baby ang magssuffer dahil di mo sya naalagaan the first months he/she needed you the most.
